Mix the base. In a large bowl, whisk together eggs, sour cream, melted butter, mayonnaise, chili powder, paprika, and garlic powder. Fold in the Jiffy mix until just combined. Pro Tip: Don’t over-mix — the casserole stays fluffier this way.
Add the corn and cheese. Stir in whole kernel corn, creamed corn, cheddar cheese, and jalapeño if using. The mixture will be thick, creamy, and slightly lumpy — perfect.
Fill the baking dish. Pour the mixture into a greased baking dish. Smooth the top lightly with a spatula.
Bake to perfection. Bake at 350°F (175°C) for 35–40 minutes, until golden around the edges and set in the center. A little jiggle is okay — it will firm as it cools.
Add the Mexican street corn topping. Sprinkle warm casserole with cotija cheese, cilantro, lime juice, and an extra dusting of chili powder. The aroma will be unreal.
Serve hot and enjoy. Scoop it like a casserole, enjoy it like elote, love it like comfort food.
